1. Product Overview

5SDD1060F0001 is ABB 1060V 1000A StakPak fast recovery press-pack diode, fully pre-assembled into standard double-sided water cooling frame 3BHL001863P0001 for medium voltage converter and generator excitation rectifier bridges. Solder-free ceramic encapsulation eliminates thermal cycling delamination failure risks; fast recovery silicon chip delivers low reverse recovery charge to reduce high-frequency switching losses under 0~1kHz modulation. Failure mode is short-circuit safe, avoiding open-circuit loss-of-excitation generator runaway hazard. Dual-surface forced water cooling supports full 1000A continuous rated load without thermal derating. Integrated mounting base for SW-6220013 FBG fiber temperature sensor provides real-time junction temperature supervision, with fault signals uploaded to AC800M DCS via ModuleBus and TB820V2 fiber modem. Widely deployed in thermal/hydro power plant UNITROL excitation cabinets, metallurgical rolling mill ACS6000 multi-drive lines and large wind grid-tied VSC converters. ABB supplies complete assembled water-cooled stack under PN 3BHL001863P0001 as official maintenance spare part.
